The construction field is increasingly adopting automation and manpower-saving technologies. However, automating all types of construction machinery is difficult because some operations require human skill and judgment-that is, professional skills-for realizing optimal work efficiency. However, the lack of competent professionals because of the decreasing and aging population in Japan is an emerging...
Hardware in the loop simulation (HILS) has been investigated in the field of the multibody dynamics (MBD), which combined the MBD simulation with the actual mechanical system. The fast simulation is necessary for the HILS system in order to require the real time simulation. This paper presents a fast simulation technique using the domain decomposition method with the iteration in the flexible multibody...
We present a dynamic simulation of a wire rope involving both contacts with a winch drum and hydraulic systems using the finite element method. Rapid winch operation often causes disorderly winding of the wire rope, which is an important quality problem. Dynamic simulation is, therefore, required for design of the hydraulic winch system on construction machinery. The wire rope is modeled using by...
